Kim Taeyeon, 18 year old in her last year of high school. She considers herself a mix between a nerd and geek. She is the top student in her class, but she's also a total dork and loves video games! She's not a popular kid and is even bullied, that is until she found a group of friends who accept her. Those friends just so happened to be pretty popular, except for her fellow nerds Sooyoung and Sunny. 

Taeyeon has never had a boyfriend or girlfriend, despite this she's a total Byuntae! Her friends about it all the time and even try to set her up on dates, but those dates always fails because of her inexperience. But this is last year of school, so she should be going out with a bang! Right? Wrong! The only thing Taeyeon is focusing on is graduating, so that she can finally be free from this prison called high school. 

Everything was going as she planned until she met her! Jessica Jung was her brother's college schoolmate and happened to tag along to visit the Kim residence one weekend. Taeyeon was finding it extremely hard to control her teenage hormones, that has remained inactive up until now, especially when she finds the college sophomore changing in her room. From then on Taeyeon knew it's going to be a long year!
